+# Quantification 模型量化、反量化
+
+## 背景故事
+部分网络如AlexNet训练出的模型体积较大，不适宜在移动设备上使用。
+
+
+## 解决模型过大办法
+1. 选用适合移动端的模型结构如：mobilenet、googlenet、 yolo、squeezenet 等；
+2. 使用我们提供的量化工具，可以在几乎不影响精度的情况下将float32模型减小至原模型的 1/4；

+#### 使用说明
+- [工具使用](https://github.com/PaddlePaddle/paddle-mobile/blob/develop/tools/quantification/README.md)
+
+## 如何读取量化后的模型
+load方法中添加了 quantification 参数，默认为false。 如果需要load量化后的模型，按需传参即可。
+

+bool Load(const std::string &dirname, bool optimize = false,
+            bool quantification = false, int batch_size = 1);

+# 模型量化脚本
+
+#### 量化脚本使用指南
+1. 在PaddleMobile项目目录下（如 ~/PaddleProject/paddle-mobile）
+
+2. cd到  tools/quantification/ 目录
+
+3. cmake编译
+
+    ``` sh
+    cmake .
+    make
+    ```
+
+4. 运行量化脚本
+    ```sh
+    ./quantify (0:seperated. 1:combined ) (输入路径) (输出路径)
+    # quantify googlenet seperated   from  /Users/xiebaiyuan/PaddleProject/quali/models/googlenet to ./googlenet_min
+    ./quantify 0 /Users/xiebaiyuan/PaddleProject/quali/models/googlenet ./googlenet_min 
+
+    ```
+
+*注:*
+*量化工具中*
+*1.seperated模型model文件默认命名为 "__model__";*
+*2.combined模型的model文件默认命名为 "model",参数文件默认命名为"params";*
+
+    
+##### 整体如下:
+以googlenet非combined为例：
+
+```sh
+cd tools/quantification/
+cmake .
+make
+./quantify 0 /Users/xiebaiyuan/PaddleProject/quali/models/googlenet ./googlenet_min
+```
